Defense attorney Robert Montgomery argued Monday that the charge of failing to remain at the scene of a fatal collision should be dismissed because he says Soules complied with Iowa law. He says Soules reported the April crash, identified himself to a 911 dispatcher, provided aid to the 66-year-old farmer, Kenneth Mosher, and waited until emergency responders arrived. He says the law didn’t require Soules to stay longer.

Prosecutor Scott Brown says the law implies that drivers responsible for fatal crashes must remain until an officer can speak with them. He says witnesses stayed longer than Soules, who fled in a truck down a gravel road about 14 minutes after rear-ending Mosher’s tractor.

Judge Andrea Dryer says she’ll rule later on Soules’ motion to dismiss the case. The trial is scheduled to begin Jan. 18.
